Where Thought Leaders go for Growth
Accounting is an important part of every business but sometimes it is also the most difficult. This is where open source accounting software comes in, as a solution that can save the day!
If you are looking for open source accounting software to handle all of your bookkeeping and accounting activities, Appvizer will show you point by point what an open source accounting software is, its benefits, its features, and we’ll even give a comparison of open source accounting software for your business.
Let's get into it now!
Let's go over a little reminder: The term "open source" means that the source code of the software is public and accessible. The software in question can then be modified and distributed by any individual.
The utility provided by open source accounting software is threefold: ease, efficiency, and autonomy.
Open source software has several advantages:
When unqualified employees use software they’re not trained in, it can waste time and sometimes lead to errors. In order to resolve this, companies sell services based on these free open source accounting software: they program them according to particular business needs, install them on-premise, and provide maintenance and support.
As for the limitations, open source software generally does not include assistance or support when learning how to use the software. Apart from forums to exchange with other users, you have to manage them on your own, and therefore master the necessary techniques to work on these kinds of tools. They also can benefit from rather innovative evolutions but this can take time to come about.
The difference between free software and open source software is not easy to distinguish. It lies in their values and in their vision.
Open source
An open source software is "open" in the sense that everyone has the possibility to access its source code. In addition to this, it is possible to redistribute the source code and create derived software products.
The Open Source Initiative (an organization founded in 1998 by Bruce Perens and Eric Raymond) focuses on technical aspects. It is compatible with the coexistence of software whose code is open but not free.
However, these days a significant part of open source software is also free.
Free software
The free software movement goes further and advocates for certain philosophical.
Described for the first time in the 1980s by Richard Stallman, and popularized by his very strong campaigns (with very strong opinions) via the FSF or Free Software Foundation, the formal definition of Free Software is based on four freedoms:
Two of these freedoms, the freedom to study how a program works and the freedom to improve it, imply access to the source code and thus that the software is open source.
